I use an older Dakine code lock that is similar to the key lock you posted. Its small enough that I can put it in a pocket without being bulky. I'm sure if someone was motivated enough they could break it and take the board but its enough of a deterrent that they'd probably look for an easier target. It does what it should.

what the above poster said.. the key lock can technically be cut with a wire cutter but its easy to carry and most people would rather look for an easier target than to carry around a wire cutter to cut through locks

same lock in a combo style can be bought at REI for like $11. That's what I use. I believe it's 10mm cable and 4' long. Burly enough where you would need bolt cutters to break it and small enough to still wrap up nicely in your pocket

Go for a combo lock. I've got like 13 pockets between my jacket and pants when I ride. The last thing I need is be looking for a key. Just a little WD40 every few trips to avoid hassles. I have one of these Wordlock 4-Wheel Cable Bike Lock : Target. Downside, you don't get to pick the word.

And as has been said on many of these threads, leave it locked on the rack at the base area.

Thanks guys. I just had a look at the Dakine Cool Lock which is a retractable combo lock.

Have you guys had any issues though like not being able to unlock the combination lock while the board was attached to a rack? That's why I was considering a key lock over a combo one although combo locks look much more convenient. Ta.
